A sterile implantable principal component of a total hip prosthesis (femoral component) designed to replace the femoral head and neck; the device is composed of two or more separate pieces (e.g., head, neck, and stem) designed to be joined and is coated with a material (e.g., porous materials, hydroxyapatite) intended to improve fixation and stability by promoting bone ingrowth. The device may be made of metal and/or ceramic materials. Fixation devices for implantation (e.g., screws and bolts) may be included and implantation may be performed with or without bone cement.
